To. all whom it may concern Be it known that l, Heroes E. 'lueor, a citizen of the United States. residing at Middletown, in the county of Butler and State of @hiou lisve invented certain new end useful. lnlproveinentsin Gus liecleinr ers; and l do herchv deelsre the following to he a full, clear, end erect description of the invention, such as will enable others skilled in the art to which it eppertoins to meke'end use the some.

The object of the invention is to provide means for useiu connection with a, gasoline or other explosive engines in which the lubrication of the piston is effected by the operation of the crank in the crank rose whereby the oil is retarded in its l'lou Wards the explosion chamber to reduce 1' carhonizution in the cylinder {necessi ing under the ordinary practice the e tivcly frequent burning out or the same) end whereby the finely divided or spru ed oil in the crank case due to the action of l crank is withdrawn from the crank o2 separated from the an and. w. are

deleterious to the bearings and niechsr sin of the engine and is returned to the creek.

case in a liquid form as a means of conserving the oil and preveutin the unnecessary wastage thcreofl without 111 any decree detracting from the efficiency oi? the motor; and with those objects in View. the lllVClliTil'lll consists in u coi'istruction and comb. is of parts of which at preferred ouih ulunent is shown in the drawings, wl'ierein- Figure 1 is a side view of the oil recleiuc ing apparatus applied in the operative position to an engine crank case and arranged in the suction line leading to the carburetor.

Figure 2 is a detail enlarged sectional view of the reclaiming apparatus.

Figure isui detuil section atright angles to Figure 2 on the plane indicated by the line 3--3 hereof.

The apparatus consists of a closed receptsclo or reservoir 10 which is arranged in and intercepts the suction line of the engine represented by the tube or pipe 11 leading from the crank case 12 to the carburetor i3 and exposed in the operation of the engine The inletenrl of the suction line is preterconnected withv an inlet opening or toe usual breather pipe of the crsnlr. case.

and the inlet opening 18 of the reservoir is located in the side Wall thereof substantially opposite as indicated to the outlet opening 19 thereof, which is in oomniuniosciou with the suction line lending to the carburetor.

In the bottom of the reservoir is a drsin pe 520 which 18 in comn'runloetion 'Wlllh nipple 21 connected by a drain return pipe or tube 25 with the crank de signed to serve as a us of convey tie ple 23 which. communicates with t outlet for the reception m": wives 26 end ll'i' which are coruiected together for simultaneous oration by means scri' to yieldingly hold suction valve 27 seated. and the outlet valve 26 unsealed us The suction valve 27 opens in the direction of suction in the line 11 so that on the suction or feeding strokes of the engine. the said velve will be unseeted to cause it reduotionoi pressure in the reservoir and hence in the crank base. which serves to retard the flow o'fluhricating oil in the cyliu den toward the explosion chamber. particularly ii there is unv looseness in the fit of the piston in the cylimler tending: to permit the rapid advance of the lubricating oil tonrds lhe explosion chamber.

lu the constructimr illustrated. the connection between said feed or suction valve 27 and the relief or outlet valve 26 consists of a hell crank lever 28 i'ulcrumed us at 29 and having its arms connected respectively by rods 30 and 31 with the said valves 2? end 26, the outlet or relief valve 26 prefe ably lacing; of such dimensions to overbaleuco the suction valve 27. so that when not subjected to suction, the Weight of the outlet valve i 56 serves to draw it swey'froin its seat and cause the seating of the suction valvef' in the operation of the device as will he 11I1dcrstoo(l.'tlie suction valve or the valve which cont oiled by the reduction oi pressure in the so. sion line due to the strokes of the piston, is 'unseeted to 2rllord communication,between suction line or cerhureter and the reservoir ot eoc-h suction indicated l ipjure 2.

stroke of the piston, until for example, the operation of the engine reaches a speed of approximately eighty revolutions per n1inute, after which the rapidity of the strokes is sutlicient to maintain the suction valve permanently unseated and the outlet or re lief valve seated, so that the effect the reduction of pressure in the suction line and through the carbureter is applied directly to the reservoir and through the latter to the crank case of the engine.

interposed in the reservoir between the inlet and outlet ports '18a'nd 19 thereof are in'ipert'orate bafiles 32 and 33 which serve to intercept the liquid oil entering the reser-,

voir in the form of spray and collect the same so that it will drop to the bottom of lhe reservoir and thence flow through th outlet or relief port 20' to the crank of the engine. In the illustrated device an intermediatehafiie or curtain 33 is inter-- posed between spaced baliles or curteins 33, the latter terminating short of thcbottom of the reservoir, while the former extendsto the bottom and is provided in its lower edge with lI-shaped notches 34 in lower edge and a slot 34 in its upper edge to permit the oil to freely flow, thereunder to the outlet 20.

In practice the device serves to withdraw from the cra'nk case all of the sprayed oil which is caused by the dash of the crank. and in addition to retarding the flow ol the oil toward the explosion chambers of the cylinders, said spray being separated from the air and gas drawn therewith from the crank case is reduced by the bullies to a liquid fl. and thence permitted to flow bltClil to the crank case for further use, and in this n .y a suhstantial economy in the use of lubricating oil is etlected, and at the same time, the gases which ordinarily are pro duced in the crankcase'zind which serve to corrodethc hearings and other parts of the mechanism are. removed before injury can result from their vnescnce.
